timex 运行系统环境

timex 语法

timex [-o] [-p [-f] [-h] [-k] [-m] [-r] [-t]] [-s] command

选件

-o

报告命令及其所有子级读取或写入的块总数以及传输的字符总数。仅当安装了过程记帐软件时，此选项才有效。

-p

列出命令及其所有子级的进程记帐记录。仅当安装了过程记帐软件时，此选项才有效。子选项f，h，k，m，r和t修改报告的数据项。选项如下：

-f	在输出中打印fork / exec标志和系统出口状态列。
-h	而不是平均内存大小，请显示进程在执行过程中消耗的总可用CPU时间的一部分。该“占用因子”计算为（总CPU时间）/（经过的时间）。
-k	显示总的内核分钟数，而不是内存大小。
-m	显示平均磁芯尺寸（默认）。
-r	显示CPU系数（用户时间/（系统时间+用户时间））。
-t	显示单独的系统和用户CPU时间。始终报告读取或写入的块数以及传输的字符数。

-s

报告在命令执行间隔期间发生的系统总活动（而不仅仅是由于command引起的活动）。报告sar中列出的所有数据项。

要执行的命令的名称

timex [-o] [-p [-f] [-h] [-k] [-m] [-r] [-t]] [-s] command

Options

-o

Report the total number of blocks read or written and total characters transferred by command and all its children. This option works only if the process accounting software is installed.

-p

List process accounting records for command and all its children. This option works only if the process accounting software is installed. Sub options f, h, k, m, r, and t modify the data items reported. The options are as follows:

-f	Print the fork/exec flag and system exit status columns in the output.
-h	Instead of mean memory size, show the fraction of total available CPU time consumed by the process during its execution. This "hog factor" is computed as (total CPU time)/(elapsed time).
-k	Instead of memory size, show total kcore-minutes.
-m	Show mean core size (the default).
-r	Show CPU factor (user time/(system-time + user-time)).
-t	Show separate system and user CPU times. The number of blocks read or written and the number of characters transferred are always reported.

-s

Report total system activity (not just that due to command ) that occurred during the execution interval of command. All the data items listed in sar are reported.

command

Name of the command to execute

timex 例子

timex -ops sleep 60

睡眠 60秒钟，并报告系统实际“睡眠”了多长时间。

timex -ops sleep 60

sleep for 60 seconds, and reports how long the system actually "slept".
